    // 接口文档：https://www.showdoc.com.cn/1834761734600444/8477923164668939

    // 功能列表
    // 功能1: 上传头像
    // 功能2: 页面初始化: 获取个人信息，并渲染到页面中
    // 功能3: 省市区的联动效果
    // 功能4: 保存个人信息，刷新页面，可以看到自己保存的个人信息
    //        说明：由于接口提供的是相同账号下的个人信息，所以当大家都在练习的时候，会出现互相覆盖的情况

    // 要求： 
    // 1. 使用 axios 发送请求
    // 2. 设置 axios 请求根路径
    // 3. 配合 async await 完成功能

    // 上传头像
    const upload = document.querySelector('#upload')
    const avatar = document.querySelector('.figure img')

    // 昵称
    const nickname = document.querySelector('[name=nickname]')

    // 省市区
    const province = document.querySelector('[name=province]')
    const city = document.querySelector('[name=city]')
    const area = document.querySelector('[name=area]')

    //1.配置请求根路径
    axios.defaults.baseURL = 'http://ajax-api.itheima.net'
    //2.数据初始化
    async function render() {

      // let cname = null
      //-----------------------------------渲染省数据
